Daru Switchgear Power-on Test Bench Test Station
Daru Electric recommends for you
1. Three-phase four-wire AC voltage 0-450V adjustable output
1.1 Connect the three-phase four-wire power supply to the power-on test bench, close the main power switch on the panel of the test bench. At this time, the "Power Voltage" voltmeter indicates the power supply voltage. By switching the "Power Voltage" switch, you can observe the balance of the power supply voltage; rotate the voltage regulator handle counterclockwise to zero. "
1.2 After the above preparations are completed, press the "Close" button of the "AC Operating Voltage" unit, the red indicator light will turn on, and the circuit is connected. Then press the "Close" button of the "Output Adjustment" unit on the lower panel, the red light turns on, the voltage regulator is powered. Rotate the "Output Adjustment" three-phase voltage regulator handle clockwise while observing the voltmeter of "AC Operating Voltage" until the required voltage value is reached; if 0-450V three-phase voltage output is needed, close the air switch next to the "Three-phase 0-380V Output" terminal on the rear wiring board; if AC operating voltage output is needed, close the air switch next to the "AC Operating Voltage" terminal on the rear wiring board, and close the air switch next to the "AC 220V" terminal on the rear wiring board to have 0-220V AC voltage output. After the test is completed, rotate the three-phase voltage regulator handle counterclockwise until the voltage is zero, and press the "Open" buttons respectively; the test is then completed.
2. Three-phase four-wire AC current 0-10A adjustable output
Connect the three-phase four-wire power supply to the power-on test bench, close the main power switch on the panel of the test bench. At this time, the "Power Voltage" voltmeter indicates the power supply voltage. By switching the "Power Voltage" switch, you can observe the balance of the power supply voltage; rotate the voltage regulator handle counterclockwise to zero. "
2.1 After the above preparations are completed, press the "Close" button of the "Three-phase AC Current" unit, the red indicator light will turn on, and the circuit is connected. Then press the "Close" button of the "Output Adjustment" unit on the lower panel, the red light turns on, the voltage regulator is powered. Rotate the "Output Adjustment" three-phase voltage regulator handle clockwise while observing the ammeter of "Three-phase AC Current" until the required current value is reached; rotate the "Three-phase AC Current" switch to read the three-phase currents separately. Note that the switch should not be placed in the "0" position at any time; when 0-10A three-phase AC current output is needed, also close the air switch next to the "Three-phase AC 0-10A" terminal on the rear wiring board. After the test is completed, rotate the three-phase voltage regulator handle counterclockwise until the voltage is zero, and press the "Open" buttons respectively; the test is then completed.
3. DC 0-260V adjustable output
Connect the three-phase four-wire power supply to the power-on test bench, close the main power switch on the panel of the test bench. At this time, the "Power Voltage" voltmeter indicates the power supply voltage. By switching the "Power Voltage" switch, you can observe the balance of the power supply voltage; rotate the voltage regulator handle counterclockwise to zero. "
3.1 After the above preparations are completed, press the "Close" button of the "AC Operating Voltage" unit, the red indicator light will turn on, and the circuit is connected. Then press the "Close" button of the "Output Adjustment" unit on the lower panel, the red light turns on, the voltage regulator is powered. Rotate the "Output Adjustment" three-phase voltage regulator handle clockwise while observing the voltmeter of "DC Operating Voltage" until the required voltage value is reached. When 0-260V DC operating voltage output is needed, also close the air switch next to the "DC Operating Voltage" terminal on the rear wiring board. After the test is completed, rotate the three-phase voltage regulator handle counterclockwise until the voltage is zero, and press the "Open" buttons respectively; the test is then completed.
(There is a discharge process for DC, be sure to wait until the ammeter indicates zero before disconnecting wires)
